Scientific title

Treating depressive symptomatology in Congolese refugees in Uganda and Rwanda: Adapting and evaluating community-based socio-therapy



Study hypothesis

1. Community based socio-therapy (CBS) intervention will be superior to enhanced care as usual (ECU) in lowering the levels of depressive symptomatology at 16- (primary endpoint) and 32-weeks (secondary endpoint) follow-up.
2. CBS will be superior to enhanced care as usual (ECU) in improving the levels of wellbeing and quality of life.
3. Refugees in the CBS intervention arm will incur lower health care costs compared to ECU group.

Ethics approval

1. Approved 22/11/2018, Makerere University (School of Social Sciences Research and Ethics Committee, Makerere University College of Humanities and Social Sciences, P. O Box 7062, Kampala- Uganda; 256 41(+256) 0414 -545040;, ref: makss rec 11.18.237

Depressive symptomatology of Congolese refugees


The Adapted Community Based Sociotherapy (aCBS) intervention is delivered in groups of 10 to 15 people living in the same geographic area (e.g. villages in camps). The aCBS intervention does not target specific diagnoses or symptoms. Rather attention is placed on being inclusive of all people in the community. Thus, aCBS minimises the potential stigma associated with disorder-focused interventions. Training and supervision for 24 facilitators across Rwanda and Uganda will be provided by CBS Rwanda (an organisation with 15 years’ experience of delivering CBS in Rwanda). The fidelity of aCBS delivery will be monitored in a subset (10%) of randomly selected sessions using an existing checklist that is completed by field staff.

Clusters of participants (e.g. villages) in the Gihembe camps and the Kyangwali (updated 22/07/2019, previously: Nakivale) settlement will be randomised to aCBS or ECU with a ratio of 1:1. Randomisation will be conducted independently by the Clinical Trials Research Centre (CTRC), University of Liverpool. The outcome of the randomisation will be communicated directly to the Trial Coordinator based at University of Rwanda. In the selected clusters, participants will be recruited through door-to-door approach. This approach has been used successfully in refugee camps in Uganda. Participants will be recruited prior to randomization of clusters. Informed consent will be obtained from participants. Outcome assessors will be blind to group allocation.

There is a theoretical possibility of contamination by recruiting refugees who might interact each other and therefore divulge intervention components from people in the experimental arm to those in the control condition. In order to minimize the possibility of any form of contamination, both the experimental and the control group will be asked to refrain from sharing study-related information and materials during the study. At all possible times during the trial, steps will be taken to organize the delivery of the intervention in a way that will prevent potential contamination.

Intervention type



Drug names

Primary outcome measure

1. Depressive symptomatology score as measured on the PHQ-937 at 16-weeks (primary endpoint) and 32-weeks (secondary endpoint) compared between the aCBS programme and ECU.

Secondary outcome measures

1. Self-Reporting Questionnaire for detecting CMDs in primary health care settings.
2. Checklist for Daily Life Stressors (CDES), WHO-5 for wellbeing.
3. WHO Quality of Life BREF, Shortened and Adapted Social Capital Assessment Tool, PTSD Check List – Screener (PCL-6) and Multi-dimensional Scale of Perceived Social Support to measure social connectivity.

Outcomes will be assessed at baseline, and at 16- (primary outcome)- and 32-weeks (secondary outcome) post-baseline. The Major Depressive Episode module of the MINI will be used at baseline only.

Results and Publications

Publication and dissemination plan

Anonymised project data will be openly available and discoverable for analysis through the UK Data Service in accordance with the ESRC research data policy. There will be a dedicated project webpage and Twitter account to provide regular updates on progress. Video presentations relating to project relevant themes (e.g. refugee mental health and wellbeing; social capital; daily stressors) will be developed to serve as educational resources (1 online resource per 4 months). These will be freely available via the project webpage. Policy briefs will be developed with the UNHCR to inform decision-making for service allocation in refugee camps. Academic papers will be submitted to high impact peer reviewed journals including but not limited to The Lancet Psychiatry, Global Mental Health, Nature reviews, Psychological Medicine etc. Members of the project team will present at academic conferences and briefing sheets will be disseminated to communicate project-related content. Implementation guidance (co-published by UNHCR and CBS Rwanda) for adapting, disseminating and evaluating aCBS for refugees in diverse settings will be developed and made available through the Institute for Community-based Socio-therapy and UNHCR web-portals. These activities will promote enhanced understanding amongst clinicians, researchers and policy makers about how to promote mental health and wellbeing in refugees at a time of unprecedented global migration.
